Answer:

x=2\sqrt{5}

Step-by-step explanation:

If that is a square, then all sides are the same. Therefore, it's a \sqrt{10} by \sqrt{10} shape. We'll use Pythagorean Theorem to find the diagonal.

a^2+b^2=c^2\\\sqrt{10}^2+ \sqrt{10}^2=x^2\\10+10=x^2\\20=x^2\\\sqrt{20}=x\\\sqrt{4*5}=x\\ 2\sqrt{5}=x

Since it's not a fraction, there is no denominator to rationalize. Let me know if you have any other questions!

First we have to convert 60 feet to inches.  since there are 12 inches in a foot we will multiply by 12
60×12=720
since the real thing is 720 inches and the scale drawing is 15 inches we can make a ratio
720:15
then simpliy
48:1
would be your answer.  It means that for every 48 inches it is in real life the scale drawing will be one inch

F(x) = 4x² + 5x - 3<br> g(x) = 4x³<br> 3x² + 5<br> Find (f+g)(x).
Dmitriy789 [7]

Answer:

4x^3+7x^2+5x+2

Step-by-step explanation:

Given:

f(x)=4x^2+5x-3

g(x)=4x^3+3x^2+5

\begin{aligned}\implies (f+g)(x)=f(x)+g(x) & = (4x^2+5x-3) + (4x^3+3x^2+5) \\& = 4x^2+5x-3+4x^3+3x^2+5 \\& = 4x^3+4x^2+3x^2+5x-3+5 \\& = 4x^3+7x^2+5x+2 \\\end{aligned}

Nancy found that x=1 is one solution to the quadratic equation (x 2)2=a. what is the value of a?
trasher [3.6K]

The value of the a in the quadratic equation is 4.

According to the statement

we have given that the x = 1 and the given equation is  (2x)^2=a

And we have to find the value of A here.

So, For this purpose, we know that the

A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared.

And the given quadratic equation is

(2x)^2 = a

we know that the x  = 1 and put the value of x in it then

(2(1))^2= a

(2)^2= a

a  = 4.

Now for rechecking of the value, put a = 4 in the given equation then

(2x)^2 = a

Put a  = 4

Then

(2x)^2 = 4

2x = 2

And the value of x become

x = 1.

Which equal to the given value of the x which is 1.

So, The value of the a in the quadratic equation is 4.
